similar conto the arm 39 of pivotcd Ell lil sleeve lrnzno 2 ment uponrotation of the spindle 15, the balls will fly outwardly to rotate thebell crank levers and to move the sleeve and flange toward the ballsagainst the force of the spring 26.

The lugs 45 and 46 on the supporting frame afford terminal supports forpiping 47 and 48, respectively, and between said lugs and piping issecured the valve mechanism 49. The valve handle 50 is disposed in thepath of the disk 01' flange 21 and, as best shown in Fig. 2, is held ina normal position thereby to close the passageway through the valve. Aspring 51 secured to the valve frame and engaging with the valve arm hasa tendency to hold this arm in the dotted position shown, in whichposition the passageway through the valve is open. Upon rotation of thespindle and operation of the governor balls the flange will be withdrawnand the arm 50 allowed to be moved toward its. alternate position by.the spring 51 and circulation may take place through the pi ing. Thevarious operative parts of t e governor may be protected by a hood 7:.engaging the 'edges of the side walls 2, '3, 4 and 5, and secured to thebase in asuitable manner.

In Fig. 5 I have shown the electromotor M utilized for driving thecompressor C, although any engine, either electrical or mechanical, maybe employed. The spindle 15 is shown connected with the motor by a belt1 6, although this connection could be direct, as by means of gearing.The compressor cylinder. issurrounded by the water jacket J which isconnected with a circulatin system, here shownas comprising the tank '5and the piping P, P, the top of the tank connecting with the top of thewater jacket and the bot tom of the tank connecting with the bottomshown'in Figs. 1 and 2.

.of the switch S connected with the supply of the water jacket,circulation being maintained in a well known manner by the difierence intemperature of the water. Interposcd in the piping 'P,.Which carries thecool water, is the valve 49, the parts 47 and 48 of the piping Pengaging with the valve, as v When the motor and compressor are at restthe valve arm 50 will be held by the flan e 21- in'position to close.passageway through the valve. Upon starting of the motor, however, uponclosure to flow from the water jacket.

cool water will As described, the tendency of the valve is always tocontinue the circulation so as to avoid any danger of the compressorever running Without water. The governing mechanism is substantiallybuilt, and the first thing to give or break would be the spring 26, andif this spring should break the f ange 21 would be unable to move thevalve arm 50 to shut off the circulation and the only harm resultingwould be continuous,

flow of water after the engine stops, this, however, being much moredesirable than to have the circulation closed upon the controllingmechanism becoming ineffective, in which case the compressor would. bein danger of destruction, owing to the failure of the cooling meanstherefor.

I do not wish to be limited to the exact construction and arrangementherein shown, as changes may readily be made without departing from thespirit of the invention.

What I claim as new and desire to secure by Letters Pa tent is:

2. In a governing device for controlling the circulation of water to thewater jacket of a compressor or other engine, the combination with avalve for inclusion in the circulating system, of a valve arm for saidvalve, spring means tending to hold said valve arm to open passagewaythrough the valve to allow circulation, centrifugal mechanism adaptedfor connection with a moving member of the compressor or other engine,said centrifugal means when the compressor or engine is atrest beingassociated with the valve arm to prevent opening of the valve, and meansupon movement of the centrifugal meansby the compressor or other enginefor causing the valve arm to be released to allow opening of said valveand consequent circulation. 3.
